Wort oxygenating equipment system and control method thereof

Abstract

The invention provides a method for controlling a wort oxygenating device system in real time, comprising the following steps of: (1) when the wort oxygenating device system is oxygenated and a wort pipe pressure chagnese, signaling a wort pressure gage to a controller which outputs signals to control opening of a wort pressure valve, thereby adjusting the wort flow; (2) re-feeding information after the wort flow is adjusted to the controller, an air pressure gage on an air pipe changing thereupon, transmitting the information again to the controller, then the controller controlling an air regulating valve and adjusting air filling flow, continuously repeating step (1) and (2), thereby adjusting the wort flow and air flow by the controller according to the wort pressure gage and a wort flowmeter.

Description

technical field [0001] The invention relates to a beer production equipment system and method, especially an equipment system and control method for oxygenating wort. Background technique [0002] In the process of beer production, oxygenation of wort is to add air or oxygen to the cold wort, so that there is a certain amount of dissolved oxygen in the wort, so as to meet the needs of yeast growth and metabolism, and can control the peak value of yeast and the rate of sugar reduction of main fermentation , beer maturity, beer flavor. Therefore, wort oxygenation equipment and methods play a very critical role in the beer production process. [0003] The existing wort oxygenation equipment system mainly includes an oxygenator and a pressure gauge, but air is directly charged into the wort pipeline, and the final dissolved oxygen in the wort is controlled to reach 8-12mg / l by manual experience. If it exceeds 12mg / l, the yeast peak value is high, the main fermentation sugar re...

AI Technical Summary

Problems solved by technology

If it exceeds 12mg / l, the peak value of yeast is high, the rate of sugar reduction by main fermentation is fast, the beer is too mature, and the flavor of beer is not good; In short, it is impossible to achieve a suitable and stable yeast peak, main fermentation sugar reduction rate, beer maturity and flavor

[0004] The disadvantage of the existing wort oxygenation equipment system is that it cannot fill the wort with oxygen in a real-time, uniform and quantitative manner in the process, so that the final wort The amount of dissolved oxygen fluctuates greatly, and it is easy to exceed the required range, and once it exceeds the target range, it cannot be adjusted, which directly affects the stability of the fermentation process
